Texas Instruments UCC21710 | Demoboard UCC21710QDWEVM-025

Description

The UCC21710QDWEVM-025 is a compact, single channel isolated gate driver board providing drive, bias voltages, protection and diagnostic needed for SiC MOSFET and Si IGBT Power Modules housed in 150 x 62 x 17 mm and 106 x 62 x 30 mm packages. This TI EVM is based on 5.7-kVrms reinforced isolation drivers UCC21710 in SOIC-16DW package with 8.0 mm creepage and clearance. The EVM includes SN6505B based isolated DC-DC transformer bias supplies.

Features

• 10-A peak split sink/source drive current for fast turn ON and turn OFF time
• 2-W bias supply with UVLO and OVLO protection set by default at 4.5 V to 5.5 V
• Drive voltages by default are 17/-5 V with single 5-V input supply
• Drive voltages can be also programmed independently from 11 V to 19 V for turn ON and from -3.3 Vto -6 V for turn OFF by using two input supplies from 3.3 V to 5.5 V
• Noise-immune design with CMTI >150 V/ns
• 5.7-kVrms reinforced isolation
• OC short-circuit shunt resistor sensing with two-level (UCC21732) or single level (UCC21710) softturn-OFF protection
• OC signal setting either for positive or negative polarity
• Desat short-circuit sensing for UCC21750
• Active Miller clamp using external FET (UCC21732) or internal (UCC21710)
• Output short circuit clamp
• Fault feedback with reset
• Isolated temperature and input rail monitoring

Typical applications

• Solar inverters, Motor drives, HEV/EV chargers, HEV/EV traction Inverters
